LGTM - saw the addition of GA for query alert suppression. Thanks for catching that @approksiu .

Thanks so much @nastasha-solomon !

#181056 description LGTM

[approksiu]

Sorry, one more addition to new features - value lists UI.

[nastasha-solomon]

@approksiu no problem! I can release-note the value list changes in 8.14 and link to elastic/kibana#179339. On a side note, it looks like our release notes tool missed 179339 because the PR doesn't have a Security team label. Our tool queries the Kibana repo for PRs with any of the release note labels (e.g., release_note:feature), the version that we specify (e.g., v8.14.0), and a Security team label (e.g., Team:SecuritySolution). If a PR is missing any of these, it isn't retrieved by our tool and won't be reflected in the release notes.

Edit: Added in 74932f5
